It all started as a despicable rumor, but now AT&T's charged ahead and made it official - its version of the Samsung Galaxy Tab will indeed cost $649, which is $50 more than the other carriers' versions and $30 more than the cheapest 3G-capable iPad. Disappointing as that may seem, a $50 virtual gift card for Samsung's Media Hub is included, as is a bunch of bloatware nobody wants (sigh).
